Non-fiction or nonfiction is created, where the author assumes responsibility for the truth or accuracy of the events, people, or information presented within it. The subject of the book, either objectively or subjectively, deals with information, events, and people in a realistic way.

Although the narrative may or may not be accurate, the specific factual assertions and descriptions can give either a true or a false account of the subject in question. However, the author will genuinely believe or claim the narrative’s content to be truthful at the time of their composition or, they convince their audience it is historically or empirically factual.

Nonfiction can also be literary criticism giving information and analysis on other works. And also informational text that deals with an actual, real-life subjects. This offers opinions or conjectures on facts and reality. This genre includes biographies, history, essays, speech, and narrative non fiction.

Common examples are expository, argumentative, functional and opinion pieces, essays on art or literature, memoirs, and journalism as well as historical, scientific, technical or economical narratives.

As a writer my favorite non-fiction book is On Writing by Stephen King. (No surprise there as he is my literary hero!)
